A man, his wife and their two teenage children were shot before the million-dollar home they were renting burned down in what investigators called arson, a fire perhaps exacerbated by fireworks and gasoline, authorities said Thursday.

The bodies of two adults and two teenagers were found inside the home at 16223 Sierra De Avila in the exclusive Avila neighborhood just north of Tampa. The house, valued by the county property appraiser at nearly $1.6 million, was destroyed in the blaze, which investigators said was intentionally set.
Darrin and Kimberly Campbell and their two teenage children had been renting Blake's house for the past two years, but investigators said they won't know the identities of the bodies found in the fire until preliminary autopsies have been performed.
